LOCOMOTIVE DRIVING BOX.

Application filed July 12, 1820.

To (ZZZ whom it may concern:

Be it known that I, rin'rriUn T. Konrixnn, a citizen of the UnitedStates, residing at Elkridge, in the county of Howard and state ofMaryland, have invented certain new and useful Improvements inLocomotive Driving Boxes, of which the following is a specification.

This invention relates to an improved locomotive driving box of thegeneral type disclosed in my copending application filed November 20,1919, Serial No. 339,3 2? and has as one of its principal objects toprovide a driving box wherein even though the wheel hub is jammedagainst the face plate employed, said plate may, nevertheless, be easilyand quickly removed.

A further object of the invention is to provide a driving box whereinthe face plate employed will be formed of sections and wherein saidsections may be removed laterally.

And a still further object of the invention is to provide a driving boxwherein the weight of the load will be employed for holding the faceplate sections against up ward movement but wherein even should thespring saddle resting upon the box break, the plate sections will,nevertheless, be firmly held in position. 7

Other and incidental objects will appear hereinafter.

In the drawings:

Figure is a side elevation of the box.

Figure 3 is a vertical sectional view taken medially through the box,

Figure l is a fragmentary top plan view particularly showing the lockinglugs at the upper ends of the scetions ol the face plate employed,

Figure 5 is a. perspective view showing one oi? the sections of the faceplate in detail, and

Figure 6 is a -fragmentary vertical section taken on the line G6 ofFigure l.

Tn carrying the invention into eiiect, I employ a box body .10 providedat its inner side with vertical flanges 11 and at its outer side withvertical flanges 12, these. flanges being adapted to cooperate forreceiving a pedestal for the box. The box body is recessed in the usualmanner to receive a drive axle and seated within the box body is aSpecification of Letters iatent.

crown brass 13 for journaling said axle. As particularly shown in Figure3, this crown brass is provided at its outer end with an upstandingarcuate stop shoulder 14: seating in a suitable recess in the outer sideof the box body for holding the crown brass against inward movement andprojecting from the outer end of the brass beyond the box body is anarcuate flange 15 located at the inner margin of the brass. Dependingfrom the legs of the box body at its inner side are lugs 16 anddepending from the box body at its outer side are similar lugs 17 whichoverhang the outer side of the box body at their upper ends to providestop shoulders 18. Fitting between the legs of the box at their lowerend portions is a shelf 19 provided with lugs 20 mating with "the lugs16 and 17 respectively. Engaged through all of the lugs at the innerside of the box body is a bolt 21 and engaging through the respectivepairs of lugs at the outer side of the box body are bolts The shell isthus rigidly secured between the legs of the box body and will serve totie the lower end portions of the legs together and brace the legs withrespect to each other. Rested upon the shelf is a grease cellar 23removably secured between the lower end portions or the legs.

As will now be observed, the box body 10 is formed at its outer sidewith an up wardly sloping or beveled outer face and overlying the outerside of the box body is a 'face plate which, as particularly shown inFigure 2, is formed with a downwardly sloping or beveled innertace'mating with the outer face of the box body. The flanges 12 are, ofcourse. beveled at their outer sides to conform to the inclination ofthe outer face of the box body and the "face plate is of a width tooverlie these flanges mating therewith. The face plate is formed of companion semi-circular sections 24.- meeting at their upper ends mediallyof the box body and upstanding from the upper ends of said sections areconfronting lugs 25 through which is engaged a tie bolt 26 rigidlyconnecting the sections. The sections of the face plate are formed tofit the flange 15 of the crown brass and at their lower ends seatagainst the shoulders 18 of the lugs 17 of the box body, and dependingfrom the sections at their lower ends are inwardly overhanging yokes 27,the inner ends of which abut the outer sides of said lugs. Asparticularly shown in Figure 2, the lower end portions of the flanges 12of the box body are, at their outer sides, provided with verticalnotches 28 to accommodate the yolres and threaded into the lugs 17 orotherwise fixed thereto are laterally projecting posts 29 over which theyolres slidably fit. The posts will thus cooperate with the shoulders 18for sustaining downward thrust upon the sections of the plate and willcoact with the yolres 27 for securing the lower end portions ofsaidscctions against outward displacement away from the outer face ofthe bolt body. Freely fitting through the box body adjacent its uppercorners are bolts 30 provided at their outer ends with flat heads 31,the inner ends of which are, as shown in Figure 6, formed withoppositely beveled edges delining at the inner end of each bolt headreversely presented shoulders. The upper end portions of the sections ofthe face plate are formed with annular recesses 32 to freely receive thebolt heads and entering said recesses are slots 33 through which thebolt heads may be projected. Further, as also shown in Figure 6, the boxbody is pro vided at its outer side with recesses 34 into whichthe boltheads may be retracted lying flush with theouter face of the box. body.Thus, by withdrawing the bolts so that the heads thereof are disposedwithin these recesses, the sections of the face plate may be securedagainst the outer side of the box body when the bolts may be projectedto dispose the heads thereof within the recesses 32. Then, by rotatingthe bolts a half turn, the bolt heads will be disposed tocoact with thebottom walls of the latter recesses so thatthe nuts at the inner ends ofthe bolts may be tightened for rigidly securing the upper end portionsof the sections against the box body. shoulders upon the inner ends ofthe bolt heads will meet with the bottom walls of the recesses 32 forholding the bolts against rotation so that the nuts of the bolts may bereadily tightened or loosened.

Formed in the upper end of the box body near its inner side is amedially disposed recess 35 and formed in the upper end of the box bodyat its outer side is a similar recess 36 arranged opposite to the recessThe recess 36 opens through the outer side of the box body, being closedat its outer side by the sections of the face plate, and seating againstthe bottom wall of said recess to fit therein are mating rearwardlyprojectinglugs 37 formed on the upper end portions of the sections ofthe face plate at their meeting ends. The recess is designed to receiveone leg 38 of a spring saddle while the recess 36 is designed to receivethe other leg 39 of said saddle. The legs of the spring saddle have beenconventionally shown.

The reversely presented Thus, as will be perceived, the leg 39 of thespring saddle will rest againstthe lugs 37 of the face plate so that theweight of the load will be utilized for maintaining these lugs seatedagainst the bottom wall of therecess and consequently holding thesections of the face plate against upward movement. Formed on the outermargin of the box body at its upper end are inwardly beveled shouldersll) lying opposite sides of the recess 36 and extending across the upperends of the flanges 12. Uverlying these shoulders are rearwardlydirected lugs all formed on the upperends of the sections ofthe faceplate above and beyond the flanges 37. flanges 41 are, as particularly.shown in Figures 2 and 3 of the drawings, provided with inwardlybeveled, lower faces mating with the shoulders 1O of the box body sothat the flanges will thus coact with said shoulders and operate inconjunction with the bolts 30 for locking the upper endportions of thesections of the base plate against outward movement away from the boxbody. Since it sometimes happens that a spring saddle breaks, whichwould, in the practical use of the present box, result in relieving theflanges 37 of the weight of the load, stud bolts 42 are fitted freelythrough the flanges 41 and threaded into the box body for securing thesections of the face plate against upward movement so that even shouldthe spring saddle break, upward thrust against the sections of the faceplate could not serve to displace saidsections. As will thus be seen,the face plate will be firmly and se curely held to the box body andsecured in a suitable dove-tailed channel in the outer faces of thesections of said plate are arcuate portions of a hub bearing 43,theportions of said bearing meeting at their upper ends and extending tothe lower ends of the sec tions. As will be readily understood, this hubbearing is disposed to confront the hub of a drive wheel and may berenewed for taking up end. play or for aiming the wheels of alocomotive.- in this connection, it is to be observed that since, asshall presently appear, the face plate may be readily removed from thebox body, I provide an arrangement wherein, by properly varying thethickness of the bearings-,3, all of the wheels of a locomotive may beeasilv and accurately alined. I v

Formed on the sections of the face plate at their outer side edgesaremedially arranged apertured lugs eldrespectively designed to receivea suitable tool for removing said sections. To accomplish this result,the load is lifted that the legs of said saddle may be lifted. The bolts30 are then loosened and said bolts retracted in the manner previouslyindicated to dispose the heads 31 thereof within the recesses 34- of thebox body. The stud bolts The i from the spring saddle so 7 LOO lit)

as are then removed and the tie bolt 26 dis placed. As will be clear,the sections of the face plate may then be lifted, as shown in dottedlines in Figure 2, to raise the lugs 3'? thereof out of the recess 36and elevate the yokes 27 above the posts 2% it being observed that thenotches 28 are of a height to permit the yolces to clear said posts.Consequently, a suitable tool may then be engaged in each of the lugsll. of the sections of the face plate and the sections removed laterallyin opposite directions. Thus,- as will be seen, the sections of the faceplate may be readily displaced and by simply reversing the operationjust described, the sections of the face plate may, of course, be aseasily again, fitted in position. In this connection, attention isdirected to the fact that since the box body and face plate are formedwith reversely beveled faces, it will be necessary to move the sectionsof the face plate upwardly but slightly before clearance will be hadbetween the face plate and a confronting wheel hub. Thus, even thoughthe wheel hub should be jammed against the face plate, the sections ofsaid plate may, nevertheless, be readily removed.
